  1. 21. On the Ecology of Saprotrophic Fungi and Bacteria in Soil: Biotic and Abiotic Control of Growth Rates

    Författare :Johannes Rousk; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decomposer ecology; soil pH; temperature relationship; Fungal growth; litter decomposition; bacterial growth; C:N;

    Sammanfattning : Two groups of organisms dominate the decomposition in soil: fungi and bacteria. One of the most important parameters to optimise for any organism is its growth, and thus a direct way to study the effect of environmental factors on fungi and bacteria in soil is to measure their growth rate.

    Sammanfattning : Mycobacterium tuberculosis (Mtb) is the pathogen causing tuberculosis (TB), a disease most often affecting the lung. 1.5 million people die annually due to TB, mainly in low-income countries. LÄS MER

  4. 23. Adaptation of Salmonella enterica to antibiotics and innate immunity effectors

    Författare :Kim Vestö; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Salmonella enterica is a bacterial pathogen causing major morbidity and mortality in low- and middle-income countries. The bacteria can cause a wide range of disease, ranging from the severe systemic disease typhoid fever to localized gastroenteritis. Characteristics of typhoid fever, caused by Salmonella enterica serovar Typhi (S. LÄS MER

  5. 24. Mechanisms of adaptation to the fitness cost of antibiotic resistance

    Författare :Wilhelm Paulander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The dissemination and persistence of antibiotic resistance, is not only depending on the volume of drugs used but also on the resistance mechanisms effect of bacterial fitness (reproductive ability). Fitness is a multifactorial parameter that is comprised of the relative growth rate of the resistant pathogen in the host and in the environment, as well as the clearance and transmission rates compared to susceptible strains.

  7. 25. Exploring the impact of antibodies on the mechanics of bacterial fimbriae

    Författare :Narges Mortezaei; Magnus Andersson; Poul Martin Bendix; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The discovery of antibiotics in 1928 seemed like a win in the battle against infectious diseases. But, the ability of bacterial pathogens to adapt to these life-saving medicines was underestimated. The bacterial evolution, indeed, led to the emergence of antibiotic resistance as soon as the clinical consumption of antibiotics started. LÄS MER
